HENRY J. HAIGHT, OF NEW YORK, N. Y.

FLAME-REGULATOR FOR BURNERS OF HEATlNG-LAMIPS.

Like letters designate corresponding parts in all of the figures.

My invention is specially designed for use on heating lamps or burners for the purpose of maintaining a constant and automatically.-

regulated heat in artificial incubators.such,

for instance, as described in myLettersPatent No. 122,249, dated December 26, 1871; but I do not confine its application to special use,

and I may use it in anyother connection where it may be applicable. t

The present invention consists in an improved flame-regulator to be placed at the sides of the wick-tube of a kerosene or other fluid burner, and to be automatically adjusted up and down for depressing the flame by coveriug or inclosing more of thewick, orincreasing the flame by exposing more of the wick, the

form and action of the regulator being such as not only to controlthe exposure of the wick, but by aproper outline given to the upper edges of the regulator when "moving on suitable pivots or centersof curved motion tokeep l the flamein proper shape in any position of the regulator. t

, The regulator is constructed substantially asfollows: Two plates, A and B, are each bent round or doubled, so as to form two sides orwings embracing the wick-tube C of the burner, one on each side thereof, as shown. The doubling is such as to bring the side wings as close as convenient to the wick-tube without rubbing. against the same or being impeded'in-its motions thereby. The bend of each plate is outside, around the edge or nar- Application filed September 12, 1881.

row side of the preferably flat wick-tube, as shown, one plate being opposite to the other. The side wings of the two plates lap by each other, as represented, the wing of one plate ordinarily being outside at one side of the wicktube, and that of the other plate outside at the other side of the wick-tube, or both wings of one plate might be outside. These wings, though close together, are not so near as to cause friction and consequent impediment in their motions. The upper edges of the several wings of these bent plates are clipped or rounded off, substantially as shown, so that as the plates are moved up and down they will present a proper and nearly uniform shape or outline to keep the burner-flame in proper form. These two plates A and B are mounted on a suitable holder, D, which is represented. as a simple ring to fit into a groove or annular depression around theburner, which may be, or

be similar to, an ordinary-lampburner, as represented in Fig. 4. Each plate is hinged to the holder at its bend b.

To one of the plates is attached a lever, E, a

which extends out through the side of the burner, and is connected at its outer end by a connecting-rod, c, with a heat self-regulator, such as described in the aforesaid Letters Patent, or any equivalent regulator. This lever moves the plate with which it is connected directly. It also moves the opposite plate indirectly, but simultaneously and equally, by having one of its Wings simplyrest on a projection, cl, on the adjacent wing of the other plate.

The operation of this regulator in an incubator is such that as the heat increases in the incubator beyond the maximum at which it is adjusted the connecting-rod c is automatically lowered, thereby lowering the outer end of the lever E, and raising the flame-regulating plates A and B and diminishing the flame of the burner. The diminution of heat in the incubator consequent thereon immediately lifts the rod 0, again depresses the plates A B, and

thus again increases the flame and heat. What I claim as my invention, and desire to secure.by Letters Patent, is- I 1.
